Title: Improvements in or relating to tuning indicators and dials for radio and like apparatus
IPC: H03J1/08
Filed: 1937-03-30
Abstract: 493,056. Adjusting wireless apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. March 30, 1937, No. 9039. Convention date, March 28, 1936. [Class 37] [Also in Group XL] A wireless receiver is provided with a frequency indicator comprising a rotatable scale or a pointer co-operating with a pointer or scale and a cathoderay resonance indicator mounted at the axis of rotation of the scale or pointer. In Figs. 1 and 2 the dial 40 carrying the frequency scale is mounted on a hub 30 rotatably mounted in apertures in the mounting plates 22, 24, on which is also fixed a gear wheel 36 engaging and driven by a toothed disc 80 mounted on the tuning condenser spindle 14. The hub 30 also carries an auxiliary dial 42 detachably mounted thereon and marked with local station names which are aligned with the corresponding frequencies on scale 40. A cathode-ray resonance indicator 46 of the " Magic eye " type is mounted on the chassis member 44 with its forward part inside the hub 30 and its forward surface flush with the dial. The dial pointer 55 is fixed with respect to the rotating dial 40 on which the wavelength or frequency scales for the various wavebands covered are marked on concentric scales. The pointer is mounted on a plate 61 which slides vertically under the control of the waverange switch spindle 20 by means of a rack 59 and pinion 57, thus to co-operate with the waveband scale in use. The cathode ray indicator is so arranged that the dark unilluminated portion 50C, which narrows to a minimum at exact resonance, is in line with the pointer 55 so that the wavelength scale and the indicator may be simultaneously observed during tuning. The tuning control shaft 70 drives the toothed disc 80, and thereby the condenser spindle 14 and dial 40, by means of a friction driving device comprising a U- shaped member 76 in the opposite limbs of which two steel balls are mounted so as to be freely rotatable. The disc 80 is forced between the balls which roll between the disc and the spring cheeks 78 of a spool member fixed to shaft 70 when the latter rotates, and the drive is thus transmitted to the disc 80. In the modification shown in Fig. 5, the dial 87 is normally fixed and carries a number of semicircular scales 87a, b, c, one for each waveband, while the pointer 85, together with the cathoderay indicator 89, is rotated by cord and pulleys from the condenser shaft 117 and control knob 123. On operating the waveband switch 99 the appropriate scale is brought to the pointer 85 by linkwork 103 and shifting gears 105. The shadow line of the resonance indicator 89 is aligned with the pointer 85 as shown in Fig. 1. Specifications 480,441 and 481,790, [Group XL], are referred to.

Abstract: 572,669. Preparation of organic disulphides. GARDNER, J. A., and MONSANTO CHEMICALS, Ltd. July 21, 1941, Nos. 9211/41 and 3236/42. [Class 41] Organic disulphides, particularly those containing thiazole or thiuram groups, are prepared by treating an aqueous solution of an alkali or alkaline earth metal salt of a mercapto thiazole or dithiocarbamic acid by electrolysis with alternating current, the hydroxide of the metal being liberated and the disulphide formed by the residues from two molecules. The solution may contain, for instance, mercaptobenzthiazole and caustic soda, or sodium mercaptobenzthiazole alone or with sodium sulphate, or the sodium salt of dimethyldithiocarbamic acid. Carbon or platinum, nickel, chromium, or nickeliron-chromium alloy electrodes are used, and the pH of the electrolyte is prevented from rising above a desired upper limit by the addition of acid or of dry mercaptobenzthiazole when that compound is being treated. The dibenzthiazyl disulphide or tetramethylthiuram disulphide produced is filtered off, washed, and dried. Specification 574,773, [Group IV], is referred to.

Title: Improvements relating to scanning circuitry
Inventor: LUCAS PIERRE
IPC: H04Q3/54
Filed: 1969-02-20
Abstract: 1,255,213. Scanning device. P. LUCAS, J. DUQUESNE, C. ABRAHAM, and R. COURTOIS. 20 Feb., 1969 [20 Feb., 1968], No. 9302/69. Heading H4K. [Also in Divisions G4-G6] To accelerate the process of cyclic scanning each row of saturable cores in a three-dimensional scanning matrix has an associated auxiliary core, the auxiliary cores being arranged as a plane of the matrix in such manner that one row of auxiliary cores corresponds to a plane of the scanning matrix proper, read out of a row of auxiliary cores in parallel indicating to a processor those rows of the associated matrix plane for which a core-by-core scan is necessary. As illustrated the matrix is addressed from an X-register 1 with decoder 19 selectively opening transistor gates 11 to 18 with an output x 1  to x k , or opening all the gates in parallel with output x 0 . The gates 11 to 18 connect readout wires common to each X-co-ordinate plane to corresponding amplifiers 41 to 48. A Z-register 3 and decoder 39 operates any selected one of transistor gates 31 to 38 to select a horizontal plane of matrix cores while a Y-register 2 by operating a gate 20 to 28 selects a single row of cores from the plane selected by the Z register. Read out is effected by a pulse from a source 6 common to the rows selected by the Y- and Z- registers. Before establishing the condition of an individual matrix core as influenced by its magnetizing winding 9, or before scanning the matrix for all such conditions, the matrix cores are reset from sources 7, 7<SP>1</SP>. Each of the matrix rows selected by a Y- and Z-co-ordinate, such as that selected by gates 28 and 31, has its energizing windings 9 commoned over isolating diodes 90 to the energizing winding 9 of an associated auxiliary core, such as 108, in the plane of the matrix defined by the Y-co-ordinate y 0 . All the rows in a plane indicated by a Y-coordinate are associated with a corresponding row of auxiliary cores in the plane y 0 ; the zth row of the yth plane being associated with the auxiliary element having its X-co-ordinate equal to z in the row with a Z-co-ordinate equal to y. To scan the matrix the output x 0  is set up from the X-register and the output y 0  is set up from the Y-register, the rows of the auxiliary plane being read out in parallel to a store 5 by sequentially stepping register Z. Any significant condition read out from a row of auxiliary cores directs the processor 10 to the individual rows for core-by-core read out.  To determine the state of an individual core in the matrix the X, Y, Z-registers are activated according to requirement and the read out result, relayed by one of the amplifiers 41 to 48, is registered on a bi-stable 4 common to all the amplifiers for inspection by the processor.
